When Lady Gaga appeared as a guest on Late Show with David Letterman Wednesday night, she had an offer Letterman and the audience couldn't refuse: a surprise historic performance.
"So I have a show across the street, and if you wanna come over, I'll bring you," Mother Monster said to letterman. "You could see the performance, I'll bring the audience."
She was referring to her final show at New York's iconic Roseland Ballroom, which will shut down after her sold-out seven night event.
